I solved this problem.
One of the wires connecting the center freezer thermistor
was open somewhere in the refrigerator so the mother board read infinity but the
display could only show -9 because the display could only
show 2 digits so this was the lowest it could show.
I rewired my thermistor with new wire and taped the wire on the freezer wall and
drilled a hole to the back of the fridge and spliced it into the connector that
went to the mother board.
This was over a year ago and it is working perfectly
